UXBRIDGE, Canada, Mar 2, 2011 (IPS)
Powerful fossil energy interests are preventing the United States from making the necessary transition to 21st century energy sources, one of the country’s leading environmental economists documents in a just-published book.
Fossil energy interests are spending “hundreds of millions of dollars” lobbying U.S. politicians in Congress and funding groups to confuse the public about the serious risks climate change poses, says Robert Repetto, author of “America’s Climate Problem: The Way Forward”.
IPS climate and environment correspondent Stephen Leahy spoke with Repetto about his new book.
Q: Why did you write this book?
A: We’re running out of time. The latest science shows that climate change is coming faster and posing greater risks than previously thought. We are at risk of triggering positive feedbacks that will lead to uncontrollable climate change.
Meanwhile, America is locked in a climate-policy stalemate, with very few in the public comprehending the real risks climate change poses. Most don’t understand that climate change is happening now. They don’t link extreme weather events we’ve been experiencing with climate change. As a result they are not demanding that politicians take action.
Q: Why don’t most Americans understand the fact that climate change is already underway and poses serious risks? Read the rest of this entry »
Canada and US Spending Billions to Create Climate Chaos
Welcome to Bizarro World
[This is a 2011 repost about Keystone XL and expansion of fossil fuel production while world's nations are supposed to be reducing climate-wrecking emissions of carbon. -- Stephen]
Analysis by Stephen Leahy
UXBRIDGE, Canada, Aug 10, 2011 (IPS)
Canada and the United States are now the centre of Bizarro World. This is where leaders promise to reduce carbon emissions but ensure a new, supersized oil pipeline called Keystone XL is built, guaranteeing further expansion of the Alberta tar sands that produce the world’s most carbon-laden oil.
“It’s imperative that we move quickly to alternate forms of energy – and that we leave the tar sands in the ground,” the U.S.’s leading climate scientists urged President Barack Obama in an open letter Aug. 3.
“As scientists… we can say categorically that it’s [the Keystone XL pipeline] not only not in the national interest, it’s also not in the planet’s best interest.”
The letter was signed by 20 world-renowned scientists, including NASA’s James Hansen, Ken Caldeira of the Carnegie Institution, Ralph Keeling of the Scripps Institution of Oceanography, and George Woodwell, founder of the Woods Hole Research Center Read the rest of this entry »
Why Our Weather is Weird ‘n Wild and Why It Is Getting Worse
Repost from 2011: More and more science reveals the not surprising connection between a warming planet and extreme weather. Won’t stop unless emissions of fossil fuels stop — Stephen

Human-induced heating of the planet has already made rainfall more intense, leading to more severe floods, researchers announced Wednesday.
Two new studies document significant impacts with just a fraction of the heating yet to come from the burning of fossil fuels. Fortunately, another new report shows the world can end its addiction to climate-wrecking fossil-fuel energy by 2050.
“Warmer air contains more moisture and leads to more extreme precipitation,” said Francis Zwiers of the University of Victoria.
Extreme precipitation and flooding over the entire northern hemisphere increased by seven percent between 1951 and 1999 as a result of anthropogenic global warming. That represents a “substantial change”, Zwiers told IPS, and more than twice the increase projected by climate modeling.
Zwiers and Xuebin Zhang of Environment Canada used observations from over 6,000 weather stations to measure the impact of climate warming on the intensity of extreme precipitation for the first time. The study was published Wednesday in the journal Nature.

The planet is currently 0.8 degrees C hotter from the burning of fossil fuels. However, global temperatures had not yet started to increase in 1951, the first year of rainfall data Zwiers and Xuebin examined. By 1999, global temperatures had climbed by about 0.6 degrees C. The average temperature increase over that 50-year period is relatively small compared to the present but major impacts have been documented in terms of storm and flood damage even with this small increase in temperatures.
This suggests that the Earth’s climatic system may be more sensitive to small temperature increases than previously believed.
Killer Heat Waves and Floods Linked to Climate Change

“The first law of humanity is not to kill your children.”

UXBRIDGE, Canada, Feb 27 2013 (IPS)
Killer heat waves, floods and storms are increasingly caused by climate change, new research reveals.
Scientists in Germany say they have found how greenhouse gases from burning fossil fuels are helping to trap the jet stream, resulting in extraordinary weather such as the 2010 Pakistan flood and the 2011 heat wave in the United States.
Human-driven climate change repeatedly disturbs the flow of atmospheric waves around the globe’s Northern hemisphere, said lead author Vladimir Petoukhov of the Potsdam Institute for Climate Impact Research (PIK) in Germany.
Giant atmospheric waves called Rossby waves are meanders in the strong, high-altitude winds known as jet streams and have a major influence on weather. These wave movements are caused by the difference in temperatures between the cold air from the Arctic and hot air from the tropics.
When the waves shift north, they suck warm air from the tropics to Europe, Russia, or the U.S., and when they swing down, they do the same thing with cold air from the Arctic, said Petoukhov.
“During several recent extreme weather events, these planetary waves almost freeze in their tracks for weeks,” he said. “So instead of bringing in cool air after having brought warm air in before, the heat just stays.”
This unnatural pattern is due to human heating of the climate through emissions of greenhouse gases that result from burning fossil fuels, according to the study published this week in Proceedings of the National Academy of Sciences.
However, this heating of the atmosphere is wildly uneven. The Arctic is warming two to three times faster than the global temperature rise of 0.8C and that affects the Rossby waves and is slowing the jet stream.
“(Our research) complements previous research that already linked such phenomena to climate change,” said Hans Joachim Schellnhuber, a co-author of the study. Read the rest of this entry »
80 percent of Arctic Ice Lost Compared to 30 Years Ago
[This is my first exclusive blog post - virtually everything else on this site are my published articles. Not sure if I'll have time to do more. Let me know what you think - Stephen ]
A new study released Feb 13 revealed that the volume of Arctic sea ice is declining rapidly. Ice volume in September 2012 had fallen 80 percent compared with the volume of ice in September 1980 according to the latest data from European Space Agency satellite, CryoSat-2. As the Arctic heats up Most of the ice loss has been in recent years. Between 2003 and 2012 the volume declined a whopping 36 percent. Summers with a sea ice-free Arctic are only a few years away, scientists now agree. This will have significant and permanent impacts on weather patterns in the Northern Hemisphere.
My previous article Ice-Free Arctic Is “Uncharted Territory” documented last September’s one year record area decline of 18 percent. Here’s what this means:
The impacts are already being felt across the entire northern hemisphere. The loss of sea ice in recent years has been affecting weather patterns, recent research has shown. The all-important jet stream – the west-to-east winds that are the boundary between the cold Arctic and the warm mid-latitudes – is slowing down, moving north and become more erratic.
When continent-sized areas of the Arctic Ocean flip from the all-white ice to dark blue, tremendous amounts of heat are absorbed from the 24-hour summer sun. When the bitter cold Arctic winter sets in over the next few weeks, all the heat in the ocean must be released into the atmosphere before ice can form again.
The Arctic will be ice-covered in winter for decades to come but what’s fundamentally changed is that every fall, unprecedented amounts of heat and water vapour will be released into the atmosphere.
“The polar meltdown shows we’re teetering on the brink of climate change catastrophe,” said Shaye Wolf, climate science director at the Center for Biological Diversity’s Climate Law Institute.
As the sea ice declines, Arctic temperatures increase, thawing more and more permafrost, which will release more climate-heating carbon and methane. Permafrost is frozen soil, sediment and rock spanning 13 million square kilometres of the land in Alaska, Canada, Siberia and parts of Europe. It has twice the carbon that the atmosphere currently holds.
A Swedish study released Feb 17 has found a link between sea ice declines and increases in methane emissions. Methane has 40x the warming of carbon. This is may lead to an even faster meltdown of the Arctic risking the release of huge amounts of permafrost carbon and methane.
US Climate Rally Draws “Line in the Sand” on Keystone Pipeline

UXBRIDGE, Canada, Feb 16 2013 (IPS)
The largest climate rally in U.S. history is expected Sunday in Washington DC with the aim of pressuring President Barack Obama to reject the Keystone XL tar sands pipeline.
Activists are calling Keystone “the line in the sand” regarding dangerous climate change, prompting the Sierra Club to suspend its 120-year ban on civil disobedience. The group’s executive director, Michael Brune, was arrested in front of the White House during a small protest against Keystone on Wednesday.
“The Keystone XL pipeline is part of the carbon infrastructure that will take us to dangerous levels of climate change,” said Simon Donner, a climate scientist at the University of British Columbia.
“By itself, Keystone won’t have much of an impact on the climate, but it is not happening on its own,” Donner told IPS.
Carbon emissions are increasing elsewhere, and the International Energy Agency recently warned humanity is on a dangerous path to four degrees C of warming before the end of this century. Children born today will experience this. Preventing that dire future is inconsistent with expanding tar sands production, Donner said.
A new study released this week revealed that the volume of Arctic sea ice is declining rapidly. Ice volume has fallen 80 percent since 1980, according to the latest data from European Space Agency satellite, CryoSat-2. Summers with a sea ice-free Arctic are only a few years away, scientists now agree. This will have significant and permanent impacts on weather patterns in the Northern Hemisphere.
“Keystone XL is the key to opening up the expansion of the tar sands industry,” said Jim Murphy, senior counsel with the National Wildlife Federation.
“By rejecting the Keystone XL tar sands pipeline, we can keep this toxic oil in the ground,” Murphy said in a statement.
Wild and Weird Weather Getting Worse

It doesn’t have to be this way – typical family could reduce their energy use 60 to 75 percent

UXBRIDGE, Canada, Jan 29 2013 (IPS)
Weird is the only way to describe January temperatures whipsawing between record warm and arctic cold over a span of a few days. Experts say that is what climate change looks like: weird, record-shattering weather.
Here’s a fact that goes beyond weird to astonishing. Anyone who is 27 years old or younger has never lived through a month that was colder than the global 20th century average. In other words, we’ve had 334 consecutive months with above average temperatures, according to the U.S. National Oceanic and Atmospheric Administration.

Last summer, the Arctic sea ice shrunk to half of what it used to be during summers only three decades ago. Our planet’s weather is driven largely by the two cold polar regions and the warm tropics. With the Arctic defrosting, it should be no surprise our weather is getting weird. And that it’s not going to get better.
Our planet is heating up because we each year put thousands of millions of tonnes of carbon dioxide (CO2) into the atmosphere by burning coal, oil, and natural gas. CO2 acts as heating blanket keeping the planet warm by trapping some of the sun’s heat.
The amount of extra heat-energy being trapped is like exploding 400,000 Hiroshima atomic bombs per day 365 days per year, calculates James Hansen, a climate scientist who heads the NASA Goddard Institute for Space Studies.
Cautious scientists like Hansen are terrified of what’s coming. Conservative institutions like the World Bank and accounting giant Price Waterhouse Coopers (PwC) have warned we’re on a path to heating the entire surface of the planet by an average of four or five degrees C before 2100. That translates into eight to 12 degrees C hotter in places like Canada.
Hurricane Sandy a Taste of More Extreme Weather to Come
By Stephen Leahy
UXBRIDGE, Canada, Nov 2 2012 (IPS)
Killing nearly 200 people in the United States, Canada and the Caribbean and crippling much of New York City and surrounding areas earlier this week, Hurricane Sandy was the kind of extreme weather event scientists have long predicted will occur with global warming.
“Climate change is a reality,” said New York Governor Andrew Cuomo after Sandy swept through his state.
Sandy was twice the size of an average hurricane, and it hit the eastern coast of the United States, where sea levels have been rising the fastest, said Kevin Trenberth, senior scientist at the National Center for Atmospheric Researchin Boulder, Colorado.
“All weather events are affected by climate change because the environment in which they occur is warmer and moister than it used to be,” Trenberth, an expert on extreme events, told IPS.
Whether climate change caused Hurricane Sandy is the wrong question to ask, added Trenberth. He explained that climate change helped make Hurricane Sandy more destructive than it otherwise would have been.
“This is the new normal,” Trenberth said. “It doesn’t make sense to rebuild in some regions – they’ll just be swept away again.”
From Sandy: ‘Saddened by Damages; Surprised You are Shocked’
I am saddened by the damage and loss of life but am truly surprised you are so shocked by the extent and severity.
Haven’t you noticed hurricanes, cyclones and other storms have become more powerful in recent years? And that extreme weather events like record flooding, droughts and heat waves are happening more frequently? In 2012 extreme weather records were broken all over the US. In 2011 there were 14 separate billion-dollar-plus weather disasters in the US including flooding, hurricanes and tornados.
